2 claims. (Cian- 35i This invention relatesto an improvement in Vwinding spindles of the character used in winding machines, lfor supporting'yarn packages, either of creases production because the operator must Y stop the winding operation on this particular spindle and unravel the bunch of yarn and then startl the operation again by fastening the yarn I.

on the cone or tube or other support on the spindle. Also in doing, Vafter. taking off the nished package, the operator must 'clean the spindle freev of al1 bunched and Wound up yarn,

no matter howsmall, because the paper tube or cone cannot be inserted to its proper place unless I the spindle is cleanthroughout its length.

rIhe object of this invention is to improve the construction of the spindle to prevent the accumulation of waste therearound between the Washer and the package,.and to eliminate the necessary Winding required for removal of the accumulation on the spindle. Y This object is accomplished by providing a conmachine, to support a yarn package thereon. The spindle I is disposed in inclined or parallel relation with respect to the periphery of-,a drive roll against which the package bears.

`The package is designated generally by the numeral 3 and is formed on a cone or tube 4 removr ablyr fitted over the spindle l and rotatable rela- V tive thereto by surface contact of the package against the drive roll therefor;

At one end of the spindle I, a Washer 5 is nor mally provided to form a stop for the tube y4 of the yarn package. I have provided an enlarged washer 6, having a peripheral wall 1 mounted on the spindley l. The washer 6 with its wall 1 are I shaped generallyconvex 'toward the yarn package;

and this washer provides a flat surface at the end of the package with the wall 1 extending divergently therefrom, esubstantially in cone shape, providing^ the convex shape referred to; VThe washer 6 is shown as secured Ain place on the Yspindle by being fitted directly thereover and abutting against the usual stop washer 5 to which vex washer of enlarged size on the spindle in position for abutment of the package support or tube thereagainst. TheA large size of this convex washer prevents the loose end of the yarn from slipping over the selvedge of the package and accumulating `on the spindle forming a bunch of yarn. By the large diameterof the Washer and its divergent peripheral wall,'a broken end of the yarn would be thrown outward by centrifugal 40 force to the winding surface of the package, in stead of Afalling onto the spindle between the washer and the package. n

I have shown a preferred embodiment of the invention Ain the accompanying drawing in which:

Fig. 1' is aside elevation of a winding spindle Y having this invention applied thereto; and

Y Fig; 2 is a detai1 side elevation thereof, partly insection. e The spindle shown is designated generally by the numeral l and isY of a general character wellknown in theart, having an enlarged shank or butt 2 adapted to be pivotally mounted in the Yusual manner onV the end of an arm of awinding the side face of the Washer 6 is welded. However, the washer may be secured in any other desired" or convenient manner tol-the spindlewithout the necessity for the washer 5.

The: spindle is used in the usual manner o i spindles that are employed in friction or drumdrive winding machines for forming a tube or coner A thereon. During the winding operation, the convex shape of the washer 6 with its Wall-1, prevents the accumulation of yarn between thewa'sher and the end of the package around the spindle. This' washer does not permit the loose end of the yarn to slip over the selvedge of the package and accumulate in a bunch on the spindle. The llarge diameter of the peripheral' wall 1 causes the broken end of the yarn to be thrown back onto the vwinding surface of the tube or cone instead of falling down on the spindleas has been the effect heretofore of using smaller latwashers. This eliminates the 'large amount of. back-wind'- ing that has been required and keeps the spindle clean, thus effecting a material saving in ytime both Yo-f the operator and thek machine particu' larly in dofng, as well .as in operation.

This improvement hasibeen used overseveral Y l months on many Vspindles of a winding machine and has been found to be a great improvement in' saving waste and` labor,"and hasmaterially in" creased production. Y

. I claim: .L

l.l` A winding device comprising Yan enlarged'ljl shankand a reduced spindle having one end fixed.

age.

2. A`winding device comprising a shank and a e spindle having one end xed to the shank and 'Y projecting outwardly therefrom toreceive a yarn package thereon for rotation relative thereto, a flat Washer surrounding an end of the spindle adjacent the shank and xed thereto, and an enlarged Washer having a hat center portion abutting, against the rst-mentioned washer normal to the axis of the spindle and xed thereto and of substantial diameter adapted to extend throughout'the area of the yarn package support, said enlarged Washer having a. frustro-conical wall l surrounding said at center portion and forming 'a convex shape inY position to face toward the package.
